Claims.

- My invention relates to improvements in. copyholders, particularly in new means for holding a sheet or number of sheets of manuscript or other writing, while being copied from by a typewriter operator whereby time and labor are saved and mistakes avoided.

My invention will be understood by reference to the accompanying drawing, where the same parts are indicated by the same numerals throughout the several views.

Fig. l is a perspective view of the copyholder with the paper holding members. 1

Fig. 2 is an enlarged side view of the paper holding member with attached weight.

Fig. 3 is an enlarged side view of the paper holding member without attached weight.

The copyholder shows the application of fingers I and 2 held in position by a support.

The fingers I and 2 are constructed preferably with a rod. This rod or finger has at its end a rubber II] which prevents the paper from slipping out underneath the finger.

Fingers I and 2 together with their supporting means 3 and 4 can be moved from AB .25 or CD respectively. Parts 3 and 4 are bent forward at II. The supporting means with fingers (paper holding clips) I and 2 slide from A to B and from C to D on bar I4. This bar I4 is through a rod I5 so constructed that the .30 two ends A and C can hardly bend and will always remain in a very straight line. This is necessary so that the supporting means 3 and 4 can easily slide from A" to B and C to D.

The same construction of bar I4 with rod I5 is repeated with bar I6 and rod I I. Bar It forms: a part of the copyholder plate I8 and is reinforced by rod IT.

The paper holding clips I and 2 are kept in position by the weight of the rod I2 which at 40 one end is bent (32 and 33) to make this rod heavier and at the same time holding it from flapping over backwards. The bent parts 32 and 33 are so long that they touch bar It when folded upwards.

The paperholding rod I2 with its finger pieces I and 2 is pivoted in its support I I.

The finger pieces I and 2 of rod I2 touches the copyplate or bar I6 above the pivoted point.

This upward inclination of the finger pieces I and 2 is the most important part of the paperholding clip. A rubber attached over each finger piece will hold any paper tight to the copyplate or bar I6. The upward inclination of the finger pieces I and 2 which can be seen especially well in Figs. 2 and 3 has the advantage that the finger pieces will open by itself if a paper is pushed underneath. No extra movement or lifting of the paperholding clip is necessary. On the other hand, once the paper is under the paperholding clips they can not be pulled down anymore. As 5 said before the support of the paperholding clip is bent out at II so that there is an eccentric action on the rubber piece of the finger and bar 55 on the copyplate.

When pulling the paper downward from under- 10 heath the fingers I and 2 the supports II would bend outwards and the eccentric action of the fingers would be lost if the supports I I would not be held in position by the fiat piece I4, over which the supports slide. Further describing the p-aper- -'1-"5 holding clip and its mounting on. the support, it is quite important that the finger parts I and 2 with the rubber pieces are standing out, away from the supports II. This allows the paper, placed on the copyholder plate to go far under the fin- :20

gers I and 2 and allows also to pull the paper on the copyplate to any height desired.

Bar I2 of the paperholding clip can not slide out of support II as on one side of support II the paperholding clip is bent backwards and on the other side bar I2 has a pin to prevent any sliding out of support I I.

The main feature of support I I is that this support is not pivoted on bar I4. On the contrary the flat side of bar I4 prevents support II from bending outwards so that the rubbers on fingers I and 2 get a very strong eccentric action on the copyplate. The more the paper is pulled downward from underneath the rubber fingers I and 2 the more the eccentric action of these fingers hold the paper tight on its place.

The operation of my device is as follows:

An unusually large sheet is placed on copyplate I8. Fingers I and 2 with. their supporting means are so designed that they can take care of unusual paper sizes. The finger supporting means Ii slide for this purpose from B to A and from D to C.

The position of fingers I and 2 shown in Fig. 1 is ready for the largest sheet. But the smallest sheet can be taken care of, if we slide the fingers I and 2 towards B and D together with their supporting means II.

These fingers I and 2 Work like eccentric levers, as shown in Fig. 2 and Fig. 3. At the end, Where they touch the copyplate they are provided with a rubber I0.

These fingers I and 2 hold in their position by their own weight.

For single small sheets the weight of the small finger itself is sufiicient and if a special copyholder for small work would be needed, such a finger could be made out of a straight piece of rod or-bar and could be pivoted at its opposite end, as shown in Fig. 3. For heavier papers or bunch of papers the weight of the fingers I and 2 has to be heavier. Bar I2 forming at one end fingers I and 2 is therefore bent at the other end, preferably backwards in such a way, that the weight of fingers I and 2 is increased. At the same time this backward bent part No. 32 and 33 in Fig. 1 and 32 in Fig. 2 holds the fingers I or 2 from turning all the way over, when a piece of paper is pushed under the rubber parts.

With other words the fingers I and 2 are by their own weight steadily pressed against the copyplate or bar I6 in Fig. 1. It is possible to slide one or several papers at a time under a finger, but it is impossible to pull the papers back. Herein is the greatest advantage. The papers may be pulled upwards. In any position the fingers are always ready to hold the paper tight. The papers may also be taken out sidewards very easily. But the more the paper pulls downwards the more the fingers will hold it. Therefore to take away a paper from underneath a finger you have to lift the finger by hand, or pull the paper away sidewards or upwards.

It is important to know that the fingers are set away from the support, so that there is space provided for the paper, in case the paper is drawn uwpards.

The object of my invention is to use the eccentric levers or fingers with the supporting means at different points of the copyplate and that the fingers with their supporting means embody a new paperholding clip which opens by itself as soon as paper is pushed underneath the paperholding clip.

Now the operator can hold the paper with both hands and place it under the paperholding clip much better, quicker and more accurately.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is:

the copy or the copyplate and said turning point being at a certain distance away from the copyplate so that the copy can easily be pushed underneath said lever, which being so constructed has an eccentric action whereby the copy holds tight on the copyplate and cannot be pulled downwards, but easily upwards and sidewards, said paper holding clips work under their own weight and are opened simply by pushing the copy underneath without being operated by hand.

2. In a copyholder, a copysupport, and means for holding a copy thereon, comprising paper holding clips and its mounting on the support, said paperholding clips being constructed in the form of eccentric levers which have the point touching the copyplate at a certain distance away from the copyplate so that the copy can easily be pushed underneath said levers but also at a certain distance away from its mounting so that the copy can be drawn upwards as much as desired.

3. In a copyholder, a copy support and means for holding a copy thereon, comprising paper holding clips and its mounting on the support, said paperholding clips being constructed in the form of eccentric levers, which are continued in a horizontal part, this part being bent backwards again, so as to give additional weight to the eccentric lever.

4.. In a copyholder, a copy support and means for holding a copy thereon, comprising paper holding clips and its mounting on the support, said paperholding clips being constructed in the form of eccentric levers, which are continued in a horizontal part, this part being bent backwards again, so as to prevent the eccentric lever from falling forwards, at the same time giving additional weight to the eccentric lever.

5. In a copyholder, a copy support and means for holding a copy thereon, comprising paper holding clips and its mounting on the support, these supports being held in position by a fiat piece of metal on which fiat piece the supports slide in and outwards, these supports being provided with means to hold the paperholding clips with their eccentric action underneath and sufiiciently above the point where the paperholding clips touch the paper on the copyplate.
